Patent number: 6854600Abstract: Active additives in absorbent articles, such as sanitary napkins, panty liners, tampons, incontinence protectors and diapers have been found to lose their properties due to taking-up moisture during storage and transportation for instance, when conventional packaging materials are used. The invention relates to the use of a moisture impervious film material for packaging an absorbent article comprising one or more active moisture-sensitive additives. Packaging is effected in film material that has low vapor and gas permeability and in packaging unites that have tight joins or seams.Type: GrantFiled: June 9, 2000Date of Patent: February 15, 2005Assignee: SCA Hygiene Products ABInventors: Charlotte Persson, Håkan Persson
